current effect in M/E 1 with the Show Alpha effect from the
Utilities group.
Applying this effect immediately causes the display on the Program monitor update,
showing the content of the alpha channel for input A (Input B is ignored).
The current input A source is keyed, so the effect displays black on Program out
reveals wherever transparency exists in the foreground, white for full opacity, and
shades of gray for in-between blends.
